The precise timing values are read from the panel EDID data for flat panels/LCDs. IIRC it's possible to make X reject the EDID timing by using a wrong refresh setting (at least that's what happened to me in the past, I had to lower the href range below the default setting), so the refresh ranges seem to get used. Modes specified in the EDID data take precedence, however. Another reason for X to reject modes is exceeding the panel dimensions. Michael
